Brad Pitt dines with Courteney Cox

The 'Fight Club' hunk joined the former 'Friends' actress – best friend of his ex-wife Jennifer Aniston – and 12 other people for their manager, Cynthia Pett-Dante's, birthday at Beso restaurant in Hollywood.

Despite Brad and Jennifer splitting in 2005, he and Courteney have maintained a good friendship, and they chatted together throughout the night.

An onlooker told website People.com: "They hugged and kissed when they greeted each other. They talked for a while.

"They were chatting, catching up. They both seemed happy and totally relaxed, very at ease. And they were both smiling the entire time. It didn't seem awkward at all."

Brad – who is now settled with Angelina Jolie, with whom he raises six children, Maddox, nine, Pax, seven, Zahara, six, Shiloh, four and two-year-old twins Knox and Vivienne - reportedly ate a steak and drank beer at the restaurant before joining other guests at the bar, who described him as "really cool".
